I To an! w/wm; u/ may concern.-

Beit known thatl, FRANK 0. BALL, a citi- Zen of the United States, residing at Muncie,

' shown and described in Letters Patent of the application 01? in the county of Delaware and State of Indiana, have invented certain new and useful Improvements iuGlass-Blowing Machines, of which-the following is a specification.

My present invention consists in certain improvement's' in'glas's-blowing machinery, and relates especially to such a machine as is United 'StatesfNo. 608,022, issued upon the ,Alvah L. Bingham July 26, 1398. l have illus'tratoda complete machine embodying my present improvements in order that the relation of the latter to the other parts of the machine maybe clearly understood, and willlincidental-ly and for purposes of clearness briefly generally describe such machine; but the'detai l description will prin- 'cipally relate to the parts involved in my present improvements. Referring tothe accompanying drawings,

which are nindel' 'a'.part hereof and on which similar letters and figures of reference indica'te similar parts, Figure 1 is a perspective ditions; Fig.3, a vertical sectional view -as view of a glass blo'wing machine provided with the improvements which constitute my present invent-ion ig. 2, a horizontal sectional view throng the standard of the machine 7, ableand pressing and blowing molds, as-seenfrom'the dotted line 2 2 in Fig. .3, showing said molds in plan in var-ions consee'n frpm t hed'otted line 3 3'in Fig. 2'; Fig. 4, a detail view showing the blowing-head and the lever for'op'erati-ng the same in elevation and also showin'gone-half a blowing-mold and a neck-'iorming mold in'thepos'itio'n they occupy standard. series of molds heretofore referred to, whichby which the heclcforming mold.(not shown in this figure) is brought accurately'to positionwhen placed upon said molds;

In said drawings the portions marked LA 5 represent the frame of a machine suitable to contain my improvements; B, a rotating ta.-

ble thereon; C, the neck-forming molds; D, I the pressing-molds;- E, the blowing-molds; F, i the plunger or perforator whereby an open ing or perforation is formed in the mass of plastic glass; G, hooks carried by the plungerhoad for lifting the neck-molds; H, the blowing-head; I, a treadle for operatingsaid blowing-head, and J a treadle for operating the latch or detent by which the rotating table is held to the proper positions.

The frame A is preferably a heavy metallic frame of suitable form-and construction and is shown as mounted on heavy trucks or wheels A. Centrallya rigid hollow stem or supported by'a collar a3, seated'in the frame A, and by a sleeve-like extension a, extending down from the bed plate of the frame A.

which carry the plunger and the blowing-' head, respectively, andthe'operating devices therefor. v e

The table B is suitably mounted on jthe bed-plate of the frame A, preferably on balls I), placed in asuitahle ball-race between them, and is adapted to revolve around the standard A, being, as is clearly shown in several of the figures,- provided with a suitable sleeve B, which extends up a considerable-distance and surrounds theadjace'nt portion of said On this ,table are mounted the in the arrangement shown consists of five of adapted to be revolved as, the work proceeds and to be accurately stopped fr0m 'time to I time atthe proper-points. There are asmany notches in the edge or ,rim of this table as there are sets of niolds. Mountedin the bededge is a latch .ordetent A, whichis operated by means of the t-read'le J. In detail'the con: i

standard A? extends np'therefrom, which is "I 5 Upon the standard A are brackets A and A,

each variety, or five. sets. The table B .is r

.plate of the frame Aadjacent'to said'rim or a neck-forming mold separately; and Fig. 8, auemu perspective View showing a-pressingmold ,a blowing'rmoldmn'dtl e adj usting-stops struction of detent -'controllin g mechanism 11 9; shown consists of a lover I, which is pivoted st 2 to the under side of the bed-plate of the perforated to receive it) to the outside of the machine. Here it is connected to a rod 3, which runs down to the trcadle J. The latchisheld into engagement by a spring-support 4, connected at one end to the treadle-arm and at the other end to the frame ofthe machine. When the treadle is depressed, the latch is drawn out of the notch in which it is at the time, and the table is free to bore volvcd. The treadle may be immediately released, as the latch or detent A will run easily along the under side of the table-rim until the next notch therein is reached into which when reached it will promptly enter, being impelled by the spring 4.

"he neck-molds C are each composed of two partsconnected together byahinge-pivot c and arc-adapted to rest upon and form a and the blowinganolds E, first of one and then of the other. The adjacent surfaces of these molds where they come together have anannular ring-and-groove formation, by which ;thciroperative surfaces are brought into proper relation vertically, asshown in Fig. 4. It is also necessary that the neckmolds be brought into proper relation horizontallyw-ith the other molds, especially with the blowing-molds. E,;RS otherwise it would be impossible to open said molds (in their present and preterred construction) without destroying or distorting the article being formed. I have therefore provided astud or projection 5 adjacent to the mold B,;into contact with which the projection p on said mold C can be thrown'and the desired position of the said molds 0 thus quickly and easily so; cured. l have also provided a similar stud or projection 6 upon the mold E, which'likewise serves as a guide and stop for the mold 0 when placed thereon. This latter is so arranged that when the molds C and E are together the pivotpoints are vertical] y in line with each other and the molds divide on the sainevertical plane, so that af tor the article has been formed and when it is desired to remove it from said molds they may open together as though they were a single mold. The interior-surfaces of these neck-molds are shaped to give the desired form to the exterior of the neck of the glass article to beformed -in the machine. The machine shown is constructed to form a varictyof fruit-jars designed for screw-caps, and consequently ,the neck-molds have inclined grooves which form appropriate screwthreads upon the outside of the necks of thev jars to enable such caps to be suitably connected to the finished jars. The two main, parts forming these neck-molds are secured together by pl v0 ts c, andeach one is provided with suitable handles C and C by which the parts may be manipulated as desired. pOne Jif thesehandleshas asuitable hook c, which Engages with a corresponding stud c on the ether, thus locking them together e haudle C is pivoted at 0 while the handle 0 is rigid; as shown. The operation is obvious.

The projection'p' is substantially opposite the base of the stiff handle C, and the points 13 of the hooks G engage with these two points,

as best shown in Fig. 7, and thus thencckmolds are substantially balanced thereon.

The pressing-molds D are cup like in form and are secured fixedly at proper points on the table B. They are adapted to receive a suitable quantity of molten glass to form one the articles being made and, in connection with the plunger F and neck-molds 0, give it its initial shape. 1

The blowing-molds E are, like the neck-- inolds E, each composed of two parts. As best shown in Fig. 4, these are pivoted together by a pivot e, and the whole mold is rigidly secured to the table 13-. For convenience sake I have shown each set of thesemolds D and continuation of both the pressing-molds D hook e which'engages with apinor stint! at e"and is provided 'witha suitable engagixzgg whereby the mold-halves cah--be locked-together when in operative position and be disengaged and separated when it is' desired to remove the article which has 'been .formed The plunger F is'of suitablesizo and shape to enter the mass of molten glass in one of the pressing-molds D and give it its initial form. -It is operatedbya. piston'contained within the cylinder F, which cylinder is carried by the bracket A on the' st-andard A As .the particular construction or this plnnger and of the means for operating it'is hott peculiar to my present invention, it will not be further described herein. A similar construction is shown in Letters Patent No; 608,022 above referred to. l i The hooks G are shown assuspended a. suitable point on. vthe head carrying the plunger F andare adapted as said plunger Ito descends to pass. beneath the neck-mold C 'andby reason or theirgf prmation (best shown n' Fig/5 to engagqwpn said neck mold 'or ring qso that as the. plunger reascends ittwill by means of the hooksputomatically lift said neck-mold and the partly-formed glassnrth cle carried thereby up,,outot and freefrom the. studs or--piyots'...'g, by; which the hook structures are carried Movemenbi of these the pressing-mold. D i as their; ob'pecially in..-Fig'. 5, thetshanks' ot "these; hooks. haw-e- :slots at their upper; 'th rough which pass structures ingone" directidii is prevented by the keepers g. .;Light springs s tcndto hold the shanks ofsaidhooks againstrthe stops termed byth'elendsfot? said k'eepers and-when the l hooks are force'd backwatdly agai hat the 'stress of saidsprings to return them quickly toposition'when the .to'roo or is 11- ciosis 3 moved. This arrangement is intended to .keepthehooks-generally in the. position shown iu'Fi' .-5,while permitting them to be moved from hat position by the application a 5, of very slight force. The result is that when the inclined lower sides'of the hooks strike fthe sides. of the neck-molds said hooks are permitted by said springs to swing backwardly easily until theipoinis p of the hooks xq are below said molds when, under the impulseof the springss, theyswing to beneath said 'neck'qnolds ready to engage with and lift them. Aportion of. molten glass and n neck 'mo'ld are not heavy; but the. plunger is'fforces the molten'glass tightly against the interior of the pressing-mold, so that it requires. considerable force to remove it, greater ;thancan be conveniently applied manually. Thcse-hooks'a'ccomplish this liitingnnd rezio have the operativeiof a considerable amount er arduous work. As they'are connected to and move with the plunger, they also serve to perform this work at exactly the right in stout of time. The books being entirely open z5npon one side and preferably with flat tops or engaging surfaces, as shown, the operative is enabled to easily remove the ring carrying the mass of partly-formed glass and deposit the same on the adjacent blowing-mold by Q haud-withbut little eifort. By my arrange nsu t, therefore, I secure that the most clifiicult portion of the work of transferring the partly-formed article from one mold to the other shall be performed automatically and by 33, the machine, while not in the least interioring with the manual manipulation necessary .totheproper carrying out of the work.

- I have shown what I conceive to be the most desirable. construction; arrangement,

"40 and means for'operating this lifting apparatus? but obviously such construction,- on ran ment, and means for operating may be ,varied from, without departing from my in-' vention.

The blowing-head His not in itself peculiar tom'ypresent invention and in general con street-ion is similar to that shown in said Letters Patent No. 608,022. it is'arranged ,above and adapted'to be seated upon the -molds when the same are completed crating the same. I A lever H, pivoted at h, is provided with engaging point-s h, which engagewith the stem carrying the blowinghead Said'lever extends through a slot to within'the hollow stem or standard A?,where it is connected with a rod H, which extends down to and connects with the arm l of the "'60 treadlel. The treadle-arm I is pivoted at ii 65,1 "easily attended to by the some person,

" which is a considerable advantage, slthongh my may be located at dificrent The operation of this machine maybe briefly described as follows Referring now to FigI-E, that operative known as the f -gatherer hits a' quantity of molten glass of the proper consistency from the furnace and deposits it in the piessing inold which is at the time at the point marked Ii 0'. 1. A. neck-forming mold or ring has oi course been placed upon said pressingmold previously. The machinewperator, who stands at the point marked No. 2, cuts off a suitable-quantity from this mass of glass. He then depresses the .treadle' J ,bulatching the latch-l, and whirls the table around until the said pressing-mold is brought below the plunger, which is directly before him. He' then (in the construction shown by means of the valvelever F causes the plunger F to operate, which, together with the neck-forming moldl 0, forms the neck of the article and also forms 7 a perforation or cavity within the mass of glass below it, forcing said massout into contact with the interior of the pressing-mold. He then reverses the plunger-operating apparatus, thus raising the plunger, which. also,

.through the hooks G, raises the neck-mold and the partly-formed gloss article. By this time a second mass of molten glass has been deposited in a pressing-mold at point No. -1. The operator then removes the neck mold or ring fromthe hooks G and deposits it on ,top

of that blowing-mold which is alongside the pressing-mold from which it has just been removed. The machine-operator again depresses the treedls J and again revolves the table, moving the, partly form'ed article around to the blowing-mold -at the point No.

3, at the same time bringing the mass of freshly-deposited molten glass from the point l0} No. 1 to the point No. 2. He then simultaneously (or approximately so) depresses the treadle I, forcing down the hlowinghead into contact with the neck-mold C at the point No. 3, the air from whichblowingfhead'ex- '1 so piste the onearticle and partially-forms socn ond. At the third opcration thecompleted article goes to the point No. Land still anothci article 18 added to the series. The completed article is either removed atthe point No. 4 or allowed to cool until it reaches the point No. 5, where in the latter case it is removed,-and the neck-forming mold is in eithercose-transferred from the blowing-mold to the pressing; IXiOlfil. ready to receive a fresh charge of molten Y 353.
